i Application filed February 7, 1910. Serial No. 542,503.

To all whom it may concern:

Be it known that I, "ROBERT 'D. Loosn, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illino1s,,have invented-certain new and useful Improvements in Mixers for In ternal-Oombustion Engines; and I do hereby declare that the following description of my said inventiomtaken in connection with the accompanying sheet-of. drawings, forms a full, clear, and "exact specification, which will enable othersskilled in the art to' which it appertains to make and use the same.

This invention'has general reference to improvements in mixers for internal combustion motors; and it consists, essentially, in the novel and peculiar combination of parts and details of. construction, as hereinafter first fully set forth and. described, and then pointed "outingthe claims.

In the drawings already. referred .to, which serve to illustrate thisinvention more fully and formya part of this specification, Figure 1 is a longitudinal sectional elevation on line a a of Fig. 2,.of this improved mixer. Fig. 2 is a sectional plan of aportion of the mixer, on line 00 a ofiFig. 1, said section line passing through-the flange of the casing andthence below the same and above the wire screen and the upper endsof the tubes.

Fig. 3 is a plan of the mixerwith the bum,

net removed. Figs. 1 and 4?, are sectional plan. views of. portions of the casingshowing modified forms of the conduits therein. Figs. 5 and 6 are diagrammatic views, of further modifications ofsaid conduitsf Fig. 7 is a viewyof a plate from which conduits may 'beformed,'and Fig. 8is a perspective view of'a' portion of, a, series of conduits constructed from a multiplicity ofthe, interlocking plates illustrated in Fig. 7.-

Like symbols and characters of reference indicate. same or similar parts in all the drawings.

The object of this invention is the production of an effective mixer for internal combustion motors, whereby the explosive mixture of liquidhydrocarbon andjair is more thoroughly mixed and better results obtained and this present invention is one of a series of improvements which I have invented andfor which applications for Letters Patent are now pending in. the United States Patent Office, this present invention having particular reference to details of construction of a mixer as disclosed in my pending application, Serial No. 535,774, filed Dec. 81, 1909, and to which reference may be had regarding the obstacles and drawbacks which I am desirous of overcoming. 1

A, in the drawings. designates a casing of suitable diameter and length. It may be circular in transverse section, or rectangular, oblong, polygonal, oval, or ovoid, ac-

cording to the space availablein internal combustion engines to 'whioh this invention is to be applied. Thiscasing is of a diameter sufliciently larger than the diameter of the'intake pipe Bofsaid engine so that its actual .area' is at least fully equal to the area of said intake pipe B. In the preferr'ed: construction, this casingcomprises an innertube 33, and an outeritube 34, to afford an annular space'3 5, which functions as a non-conductor of heat in the well-known manner. At the'b ottom of'this casing there gine cylinder 'or' cylinders of said motor.

These passages or conduits 15, are produced in various -mann'ers, the "preferred method being by the employment 'of plain round tubes 16, as shown in'Figs..1,-2, and 3, said tubes being. arranged close together and approximately filling the innerytube 33, and secured together in any approved manner, but they may "also be formed by rectangular passages 15*, as illustratedin Fig. 4-; or 15', as shown in Fig. 4 and polygonal conduits 15, as shownin Fig. 5, while the rectangular conduits may readily be .made from plates 17, as indicated in; Fig. 7, said plates 17 having slots 17 reaching to one half of the width of the plates, thenon-slotted portion being inserted in the slots of the respective plates. so as to form the rectangular conduits 15*, as indicated in Fig. 8. These rectangular conduits may, furthermqra'be produced from crimped sheets 27, as indie cated in Fig. 6.

The walls of the conduits may be non perforated, but I prefer that they be provided with a series of comparatively small holes 25, as illustrated in Fig. 1, which holes form capillary cells adapted to temporarily retain liquids, as will hereinafter more fully appear.

The upper end of the casing A has a flange 18, in the face of which there is an annular recess 30, Figs. 1 and 3, in which there is located a plate 18, having a series Fig. 1, in which there is located a circular disk, 20, having a series of openings 21, corresponding to the shape of the openings 19; a handle or other suitable means 22, projecting from said disk 20 being provided to afiord means for oscillating said disk 20, which thereby serves as a cut-off in the wellknown manner.

In order that the conduit-structure in the casing A may be removed therefrom, should such removal become necessary or desirable, I locate these conduits in a tube 24, Figs. 1 and 4, which tube 24 slides into the inner tube 33, when the plate 18, disk 20, and

the bonnet 13, are removed from said casing, said tube 24 having wire screens 32 at its ends made from comparatively thin wire and wide-mesh, to retain said conduits in said tube 33, or in the tube 24, as the case may be, when the tube 33 is not being employed.

It will now be observed that both, the interior of the conduits as well as the interstices 15 between the conduits form passages for the explosive ascending mixture, which passages are straight and practically unobstructed. The function of these comparatively small passages is to break up the bulk of the ascending mixture into a large number of small columns. Any liquid matter, such as water, or unevaporated hydrocarbon carried by said mixture is retained in the cells 25 in the conduits until evaporated, so that said mixture'after having passed through said conduits is freed from moisture and thoroughly mixed.

I desire to place emphasis upon the fact that in the preferred embodiment of this invention both, the interior of the conduits, and the interstices between these conduits through which the mixture ascends from passages for said mixture, so that only the lower, comparatively thin edges of these conduits are presented to the ascending mixture, whereby but a trifling and negligible obstruction is offered to the ascending mixture when entering said conduits.

In Figs. 1, 2, and 3, I have illustrated conduits formed of round or cylindrical tubes, and I have shown these tubes in several diameters in order to illustrate how tubes of different diameters may be used in the mixer. I desire it to be understood,

however, that in practice there'will be but conduits to illustrate several modifications thereof, all of which I believe to be equally Yeficient in service. of openings 19; and a further recess 30,

Having thus fully described this invention, I claim as new and desire to secure to me by Letters Patent of the United States 1. A mixer for internal combustion enl'gines, comprising, in combination, a casing,

means at the top and the bottom of said casing whereby said casing'is adapted for connection to the intake pipe of such-engine, a regulating valve insaid casing, a series of conduits in said casing occupying the entire interior space in said casing and affording a series of straight and unobistructed passages in said casing through said conduits and through the interstices between said conduits, said conduits having in their walls minute spaces adapted to re tain moisture by capillary attraction, said conduits presenting to the ascending explosive mixture the narrow edges only, and means above and below said condults to retain them in said casing.

and unobstructed passages in said casing through said conduits and through the interstices between said conduits, said conduits presenting to the ascending explosive charge their narrow edges only, means for retaining said conduits in said casing, and means at the upper end of the casing for regulating the discharge from said casing.

3. A mixer for internal combustion engines, comprising, in combination, a casing, means atthe upper, and at the lower ends of said casing for connecting the same to the intake pipe of said engine, a conduit-- retaining tube within said casing, a series of conduits in said conduit-retaining tube occupying the entire interior space in said conduit-retaining tube and affording a multiplicity of straight and unobstructed passages in said casing through said conduits and through the interstices between said conduits, said conduits presenting to the ascending explosive charge narrow edges only, means above and below said conduits for retaining them in said conduit-retaining tube, and means at the upper end of said i the openings in said Wall, and means on said Attest:
